Alpha SL 2-20 is a gypsum-based, self-leveling leveling mortar for indoor use. It is suitable for calcium sulfate-based substrates, such as anhydrite or alpha-hemihydrate floors. It is easy to apply and pumpable for thicknesses between 2 and 20 mm. Alpha SL 2-20 can be used over underfloor heating, is low-shrinkage and low-tension, and hardens quickly.

Alpha SL 2-20 is not suitable for wooden substrates, industrial applications, or permanently damp areas. This leveling compound is an underlayment and must be finished with a floor finish.
